My fellow characters and I are exploring a lost city buried beneath the sands of a vast desert. Shortly into our first foray, we come across a well-appointed dining chamber and its occupant, a friendly and immaculately dressed fellow who invites us to partake of refreshment. He is joined by several servants who attend to us. Hospitality is big in the culture of this region, and though it's a bit odd that this dude and his servants are in this buried city, it's the first friendly face we've seen in a while.
Bowls of fruit and wine are brought out. My character, Brickyard Lot, has a flaw that reads: "If I see fruit, I eat it." This has notably gotten him into trouble before (and the party doesn't trust him with pocket goodberries). Anyway, naturally I'm eating the fruit before the bowls can be set down. "A wave of exhaustion washes over you," says the DM. "Make a Con save." I roll the dice and succeed, belching and happily continuing to eat.
The food and drink is offered to my comrades, of course, but having seen me need to roll a save, nobody wants to partake. Does anyone see any issue with this refusal? If so, what are the issues and how do you resolve them. If not, why not?
Let's consider another angle as well: Say my character has the aforementioned flaw, but isn't the first to eat the fruit. I witness another character make a saving throw after eating it. I then refuse to eat the fruit or drink the wine, despite the flaw. Does this change the calculation at all as to whether this is an issue that needs to be addressed?
